DESCRIPTION
Citric Acid E330 is a naturally occurring tricarboxylic acid found in citrus fruits and widely produced commercially by fermentation for food, pharmaceutical, cosmetic, and industrial use.
Citric Acid E330 contains three carboxylic acid groups and one hydroxyl group, giving Citric Acid E330 strong acidulant, buffering, and metal-chelating functionality.
Citric Acid E330 is widely recognized as food additive E330 when used as an acidity regulator, acidulant, and flavor-support ingredient.
Citric Acid E330 dissolves readily in water and produces an acidic solution that can adjust pH in beverages, foods, cosmetics, cleaners, and pharmaceutical systems.
Citric Acid E330 can bind metal ions such as calcium, magnesium, and iron, which helps reduce scale formation, improve cleaning performance, and protect sensitive ingredients from metal-catalyzed degradation.
Citric Acid E330 can work with citrate salts such as sodium citrate or potassium citrate to create buffer systems with controlled pH.
Citric Acid E330 should be selected according to the intended grade because food, pharmaceutical, cosmetic, and industrial applications require different purity, particle size, and contaminant specifications.
Citric Acid E330 should be protected from moisture because the crystalline material can cake, harden, or lose flowability under humid storage conditions.
Citric Acid E330 should be used according to food additive regulations, pharmaceutical standards, cosmetic GMP, detergent regulations, workplace safety standards, and final product performance requirements.

Avoid breathing dust during weighing, transfer, blending, and packaging operations.
Skin Contact:
Wash skin with soap and water after contact.
Seek medical advice if irritation, redness, dryness, or prolonged discomfort develops.
Remove contaminated clothing if necessary and wash before reuse.
Eye Contact:
Rinse cautiously with water for at least 15 minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation, redness, pain, or blurred vision persists.
Ingestion:
Rinse mouth with water.
Seek medical attention if a large amount is swallowed or if discomfort occurs.
Do not use industrial grade material for food, pharmaceutical, or supplement consumption.
Note to Physicians:
Treat symptomatically.
Monitor for irritation of the mouth, throat, gastrointestinal tract, eyes, skin, or respiratory tract after significant exposure.
Provide supportive care as needed.
HANDLING AND STORAGE
Handling:
Use appropriate PPE including gloves, safety glasses, and dust protection where bulk powder exposure may occur.
Avoid generating dust during transfer, weighing, charging, milling, and blending operations.
Use clean, dry equipment to prevent contamination and maintain food, pharmaceutical, cosmetic, or industrial grade quality.
Ventilation:
Use general ventilation for normal handling.
Use local exhaust ventilation where dust may be generated.
Avoid inhalation exposure during bulk powder transfer and high-speed blending.
Storage:
Store in tightly closed containers in a cool, dry, well-ventilated area.
Protect from moisture, humidity, excessive heat, direct sunlight, and contamination.
Keep away from strong bases, oxidizers, carbonates, bicarbonates, reactive metals, and incompatible chemicals.
Spill and Leak Procedures:
Avoid dust generation and collect spilled powder using vacuum or careful sweeping methods.
Place material into suitable containers for reuse or disposal according to quality status and local regulations.
Clean remaining residue with water if allowed by facility procedure because acidic residues can affect sensitive surfaces.
Handling Precautions:
Control moisture because Citric Acid E330 can cake, harden, or lose flowability when exposed to humid air.
Control pH carefully because Citric Acid E330 strongly affects acidity, preservative performance, flavor, chelation, and compatibility with carbonate or mineral ingredients.
Rotate stock using FIFO practices to maintain consistent purity, particle size, color, odor, moisture level, and formulation performance.
